Ms Gillard maintains the figures are genuine and says Mr Pyne is 100 per cent wrong.

Queensland's Education Minister John-Paul Langbroek also says it is a cynical and inappropriate attempt to put pressure on his Government.

"There's no doubt Prime Minister Gillard thinks this is a way to conjure up an election victory," he said.

"I think the people of Queensland and the people of Australia are a bit smarter than that and they're not going to try to blackmail the Government of Queensland into signing up for a deal until we can check that the figures stack up.

"[It] doesn't convince us that they are actually interested in anything other than their own political survival."
